2-D Encoded Multiplexing Readout for THGEM

Micropattern gas detectors (MPGDs) have a wide application in high-energy physics, astrophysics, nuclear physics, medical imaging, and so on. The demand for large area and good spatial resolution requires a large number of channels. The conventional 2-D tracking for MPGDs requires a large number of electronic channels, and in consequence poses a big challenge for the integration, power consumption, cooling, and cost, which has become a problem to the further applications of MPGDs. In this paper, a new tracking method for MPGDs based on 2-D encoded multiplexing readout is presented, which is easily extensible and can significantly reduce the number of electronic readout channels.
